Abstract
The utility model relates to a fluted plate wave regular packing. The regular packing is formed by the folding of wavelike thin bands, and diamond grooves are arranged at the wave troughs, the wave peaks, and wave antinodes of waves. Both sides of the direction of the band length of each of the grooves are cut to be open, and the other two sides are connected with the band. The grooves are recessed towards the opposite directions of the wave peaks and the wave troughs at the wave peaks and the wave troughs of the bands, and a concave corrugation parallel to the direction of the band length is arranged between two rows of the grooves. The regular packing designed by the utility model raises the productivity and the mass transfer efficiency and reduces the resistance of packing layers.
Description
The utility model relates to the structured packing of a kind of fluted sheet ripple, belongs to the gas-liquid mass transfer (contact) equipment field in oil refining, petrochemical industry, chemical industry, light industry and the environmental protection, is the critical piece in rectifying in the above-mentioned industry, the absorption tower.
Most widely used structured packing is perforated plate corrugated filler (Melapak sees Fig. 1) in China's industry at present, and this filler mass-transfer efficiency is higher, and production capacity is bigger, and pressure drop is very low.But its limitation is also arranged, and not enough to wetting (adhesion) property of liquid as its surface, the distribution of surface liquid is perfect inadequately, and filling surface has washed out 8～12% circular hole, can not participate in the gas-liquid contact, reduce effective contact area, thereby influenced the further raising of its mass-transfer efficiency.
The purpose of this utility model is the structured packing of a kind of fluted sheet ripple of design, changes the structure and the shape of prior art, and the production capacity (liquid flooding gas speed) with further raising structured packing improves its mass-transfer efficiency, reduces the packing layer resistance.
The fluted sheet ripple structured packing of the utility model design is formed by stacking by the waveform strip, the crest crestal line of every strip and belt length direction are 120～135 ° of angles, trough, crest and antinode at wave, have the rhombus groove, cut on belt length direction two limits of groove, other two limits and band link, groove is to lower recess 0.5～0.8mm, crest and trough place at band, groove is to the rightabout depression of crest, trough, between two row grooves 1～3 dimpled grain parallel with the belt length direction is arranged, its degree of depth is 0.5～1mm.
Use the fluted sheet ripple structured packing of the utility model design, compare, have the following advantages with traditional perforated plate corrugated filler:
1, because the groove line of this filling surface uniqueness, its surperficial wettability, liquid are much improved in uniformity, the penetrability of liquid between the filler tow sides of surface distributed, strengthen the turbulence of liquid (this has simulated experiment and has confirmed) thereby can make full use of filling surface, therefore can improve mass-transfer efficiency.
2, because hole area 8～15% is beaten on the perforated plate corrugated filler surface, this part causes the mass transfer area loss, also wasted metal, and all ducts of this filler is associated in all on the filler body, thereby the mass transfer area of this filler improves 8～12% than perforated plate corrugated filler.
3, the peak of traditional ripple packing, paddy are acute angle, and owing to capillary effect, liquid easily is gathered in the lowest point and flows down herein, form channel (being many experiment confirms), thereby make the liquid distribution inequality, have reduced mass-transfer efficiency.And the utility model filler peak valley is a circular arc, has therefore reduced capillary influence, helps the even distribution of liquid.
4, because crest, trough dash darker groove is arranged, can form the passage of air-flow lateral flow herein, thereby horizontal (radially) of air-flow diffusion has better reduced radially concentration gradient, help mass transfer, also help reducing fluid resistance (pressure drop) and increase production capacity.
5, the uniformity that distributes owing to gas-liquid is so amplification efficient is very little.
6, because filler band upper punch has many " groove lines ", each groove constitutes domes, so this filler has better rigidity.
7, in sum, the more traditional perforated plate corrugated filler of the wavy filler of groove line band has mass-transfer efficiency height (can improve 10～15%), (can reduce 10～20%) lowered in pressure drop, its separating power can improve 10～20%, can improve production capacity, the product quality of mass transfer operations such as distillation, absorption, cut down the consumption of energy.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the fluted sheet ripple structured packing stereogram of the utility model design.
Fig. 3 is the expanded view of a filler band.
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.
Among Fig. 2～Fig. 3, the 1st, groove, the 2nd, dimpled grain, the 3rd, crest, the 4th, antinode, the 5th, trough, the 6th, crest crestal line.
As shown in Figure 2, the fluted sheet ripple structured packing of the utility model design is formed by stacking by the waveform strip, the crest crestal line 6 and the belt length direction of every strip are 120～135 ° of angles, trough 5, crest 3 and antinode 4 at wave, have rhombus groove 1, cut on belt length direction two limits of groove, and other two limits and band link, and groove is to lower recess 0.5～0.8mm.At the crest and the trough place of band, groove is to the rightabout depression of crest, trough.Between two row grooves a dimpled grain parallel with the belt length direction 2 is arranged, its degree of depth is 0.5～1mm.
Substantially the metal strip that is configured as curving the inclination ripple of this filler is by adjacent two assemblys of being with the ripple directions to be formed by stacking on the contrary.Be divided into cylindrical or become to be divided into bulk according to the tower body size, vertically be installed in the tower by two layers of filler band direction up and down.
Fluted sheet ripple of the present utility model structured packing can be adopted material manufacturings such as metal, plastics, pottery.For sheet metal, beat groove through punching press, bend to waveform, promptly get filler waveform band, then many waveform bands are overlapped into the packing box or the piece of required form by each band ripple direction opposite principle, are installed in the tower by the principle of staggered 90 ° of two layers of filler waveform band up and down.
